    Excerpt: ... CM 4310, Chemical Process Safety /Environment Homework #1 Fall `08 Mon. 01 Dec., '08 1. Global Energy Balance. Problems 2 and 3 Chapter 1, page 32 and 33. 2. Partitioning of Pentachlorophenol in a Pond Problem 5 of Chapter 5. This is the same problem as shown in lecture, except in this problem assume that the pollutant is pentachlorophenol. You'll need to look up the CAS number for this compound. 3. Mackay's Level III Multimedia Compartment Model : Model Sensitivity. Any model of environmental behavior of chemicals needs to be validated for accuracy. One important step in this evaluation is to understand the sensitivity of the model to changes in input parameters (e.g. Henry's Constant, KOW, reaction half lives, etc.). Use the data in Example 11.2-1 in order to evaluate the sensitivity of the level III model to a doubling and a halving in the value of ONE of these parameters. State clearly which chemical you are choosing (benzene, ethanol, or pentchlorophenol), which environmental property you varied, and ...

    Excerpt: ... CM4310 Reactive Chemicals October 20, 2006 Chemical Process Safety Chemical Reactivity Reactive Chemical Hazards What? Reactive chemicals contain a lot of energy. When this energy is released suddenly and unexpectedly, an accident may result. Why? Reactive chemical accidents are unfortunately, fairly common. Problem? Reactive chemicals are difficult to quantify in a general fashion. Reactive Chemical Hazards The U.S. Chemical Safety and Hazard Investigation Board completed a study of reactive chemical incidents in 2002. They found that 167 reactive chemicals accidents occurred between 1980 and 2001, resulting in 108 fatalities. They also found that current regulations did not adequately cover these hazards. Incident April 21, 1995 5 worker fatalities ~300 evacuated Facility destroyed Surrounding businesses damaged Ed Hill, The Bergen Record Used with permission Reactive Chemical Hazards The uncontrolled chemical reaction might be accompanied by: Temperature increase Pressure ...
